The Data Scientist’s Toolbox is the first course in the “Data Science” specialization available from Coursera. The specialization itself will be very interesting to complete. The point of the specialization is to learn how to use R to perform statistical analyses in a professional environment. You will learn how to use R and how to work with and prepare data in a professional manner.
Unfortunately to earn a certificate in the specialization you must take this class. In reality, this class should be combined into the next class which is R Programming. Basically the class provides an overview of the entire specialization and instructions on how to get setup with the various applications. My guess is that the average person that is taking these courses will have no problem setting up the required software and getting up and going. So that makes this class similar to a general education course at a university. In other words, it is a class you are required to pay for that has some interesting information but in general isn’t worth the time.
In summary, if you don’t plan on completing the entire specialization then don’t bother paying for this class. It will help you get up and running but beyond that it really doesn’t help much.
If you do pay for the course then you get a certificate.
